Notifier NC-100R is an addressable relay module that provides two Form-C dry contacts that switch together. It is intended for addressable, two-wire systems, where the control panel switches the discrete contacts by code command.
According to the manufacturer's data sheet, the NC-100R(A) relay module is made for Notifier FireWarden Series intelligent control panels. The relay provides two isolated sets of Form-C dry contacts, so one command operates both sets at once.

Application notes
- Use the NC-100R when the panel needs to switch equipment contacts, not monitor them. For monitoring a normally-open contact, a monitor module is the right device.
- Check the contact rating against the load, including whether the circuit is coded or non-coded, before wiring.
- Confirm panel compatibility before ordering. The data sheet describes the module for FireWarden Series panels.

FAQ
Which panels is the NC-100R for?
Notifier FireWarden Series intelligent control panels: addresses 01–99 on the FireWarden-100-2(C) and 01–50 on the FireWarden-50(C).
What can it control?
Its two Form-C dry contacts can operate door holders, air handling unit shutdown and similar equipment, and can reset four-wire smoke detector power.
How is it mounted?
It mounts to a 4 in. square box 2.125 in. deep; the SMB500 is the optional surface-mount backbox.
Does it need an end-of-line resistor?
No. The data sheet lists EOL resistance as not used; the relay and circuitry are powered directly from the two-wire SLC.
